announced via advisory DSA 1533-2.

Christian Schmid and Meder Kydyraliev (Google Security) discovered a
number of vulnerabilities in exiftags, a utility for extracting EXIF
metadata from JPEG images. This update merely adds the packages for
Debian 3.1 sarge (oldstable) which were missing in the previous DSA.

The Common Vulnerabilities and Exposures project identified the
following three problems:

CVE-2007-6354

Inadequate EXIF property validation could lead to invalid memory
accesses if executed on a maliciously crafted image, potentially
including heap corruption and the execution of arbitrary code.

CVE-2007-6355

Flawed data validation could lead to integer overflows, causing
other invalid memory accesses, also with the potential for memory
corruption or arbitrary code execution.

CVE-2007-6356

Cyclical EXIF image file directory (IFD) references could cause
a denial of service (infinite loop).

For the stable distribution (etch), these problems have been fixed in
version 0.98-1.1+etch1.

For the oldstable distribution (sarge), these problems have been fixed
in version 0.98-1.1+0sarge1.

For the unstable distribution (sid), these problems have been fixed in
version 1.01-0.1.
